Transfer Path Analysis Overview

LMS Test.Lab Transfer Path Analysis

LMS Test.Lab Transfer Path Analysis

Understanding the root causes of noise and vibration problems The LMS Test.Lab Transfer Path Analysis solution provides a systematic approach to test-based engineering processes and focuses engineering efforts on the components that matter the most. As a method to fully understand vibro-acoustic behavior, TPA assists in troubleshooting vibro-acoustic issues and setting performance targets for each critical component. In complicated structures with various sub-assemblies (such as cars, aircrafts ...

Single Reference Transfer Path Analysis and Airborne Structure

Single Reference Transfer Path Analysis and Airborne Structure

LMS Test.Lab Single Reference Transfer Path Analysis helps engineers trace the flow of vibro-acoustic energy from a source, through a set of known airborne and structure-borne pathways, to a given receiver location. The solution supports contribution analysis for single source noise or vibration issues, during stationary or run-up and run-down operating conditions. Airborne and structure-borne paths can be analyzed together or separately, using frequency response functions and operational data....

Multi-reference Transfer Path Analysis

Multi-reference Transfer Path Analysis

LMS Test.Lab Multi-reference Transfer Path Analysis supports contribution analysis for multi-source noise and vibration issues. The complex analysis of multiple partially-correlated sources is reduced to multiple analyses of independent, uncorrelated sources by using singular value decomposition. The final analysis will recombine the results of the individual sources to investigate their combined effect on the target location. The solution is particularly adapted to road noise analysis. It helps ...

OPAX

OPAX

The unique LMS Test.Lab OPAX solution is a fast, test-based procedure which supports troubleshooting of vibro-acoustic problems in a very efficient way. LMS’ breakthrough approach is nearly as accurate as conventional transfer path analysis and almost as fast as traditional operational path methods that often fail to identify the root cause of vibrations and find remedies to NVH problems. The LMS Test.Lab OPAX solution separates loads and transfer paths so that vibro-acoustic energy can be traced ...

Time Domain Transfer Path Analysis

Time Domain Transfer Path Analysis

LMS Test.Lab Time Domain Transfer Path Analysis is a solution to identify transfer paths in the time domain. This solution provides accurate identification of transfer paths related to a specific event in the time domain. LMS Test.Lab Time Domain TPA lets engineers analyze transient phenomena. Users can listen to the partial path contribution and compare it to the target sound. The path contributions are not reflected as spectra but as time-domain contributions. Time domain TPA complements frequency ...
